PHP Version 5.4

We are pleased to announce the deployment of PHP 5.4 on our newest servers. While the default PHP version will still be 5.3 on these servers, customers will have the option to switch to between three versions of PHP: 5.2, 5.3, or 5.4. For step-by-step instructions on how to change your PHP version through cPanel, please see our tutorial How to Switch Between PHP Versions.

If you are currently on a server that does not support newer versions of PHP but would like to use either PHP 5.3 or 5.4, please submit a request to our Support Department to request an account move to a server that supports PHP 5.3 and 5.4. Please make sure you include the cPanel user name or main domain name on the account along with account verification (either your AMP password or last 4 digits of the credit card on file).
